1994 90 hp sportjet

I just bought a 1994 Bayliner Jazz 90 Hp sport jet. Has weak intermittent spark, previous owner replaced, stator, trigger, switch box and I replaced voltage regulator. Any info is appreciated!

test the coils.

is the weak spark on all plugs, or only 1 or 2?

Weak spark on either one or two, it jumps around sometimes there’s no spark

First check the battery?
Deep cycle? not good in a starting application.
Regular battery, not turning it over fast enough?

outboardignitiondotcom has test procedures for your motor.
Even a new stator can go bad in 10 seconds.

Thanks, I’m leaning towards stator or switchbox.
